Understand Your Home's Runoff

Rainwater on Your Property

As our area grows, where there was once land covered by mostly forest, we now have hard surfaces such as roofs, asphalt, and pavement. When rain falls on these hard surfaces, it cannot soak into the ground so it quickly becomes runoff that can cause flooding in our streets and homes.

Rainwater picks up what it touches on your property, like oil from the road, yard chemicals, and pet waste. This unfiltered, polluted water runs into our storm drain systems and flows into our streams, lakes, and Puget Sound. This polluted water can be highly toxic to our fish and wildlife.
